ACPICA: Fix for implicit result conversion for the ToXXX functions
ACPICA commit e1342c9f2dde37a67e916099658b65984ef8a434 Implicit result conversion was incorrectly disabled for the following functions: FromBCD ToBCD ToDecimalString ToHexString ToInteger ToBuffer Link: https://github.com/acpica/acpica/commit/e1342c9f Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

+ * to_decimal_string
+ * to_hex_string
+ * to_integer
+ * to_buffer
+ * The purpose of this type was to disable "implicit result conversion",
